Cursor Measurement; Voltage Measurement - Tenma 72-14520 Instructions Manual

CURSOR MEASUREMENT

• The cursor can be used to measure the X axis (time) and the Y axis (voltage) of the
selected waveform. Press the CURSOR button to enter the cursor measurement
menu.
Time Measurement
• Press the CURSOR button to enter the cursor measurement menu. Then press the
F1 key to select the type to measure.
• Press F2 to select the source of the time measurement channel and set the pattern
to independent.
• The multi-purpose control can adjust the vertical cursor AX, press it to switch to
cursor BX.
• The measured values are shown in the upper left corner of the waveform display
area. The value of BX-AX is the time measurement, and 1/|BX-AX| is the reciprocal
of time, or frequency.
• For a periodic signal, if AX and BX are set at the rising edge of adjacent cycles,
then BX-AX is the signal's period, and 1/|BX-AX| is the frequency.
• Parameters can also display the voltage value at cursor's current position. That is
AY, BY, and BY-AY.
• The multi-purpose control can be used to adjust the BX and AX positions when
setting is set to trace using the F3 key.

VOLTAGE MEASUREMENT

• The method for voltage measurement is similar to the method for time
measurement, only that the vertical cursor becomes the horizontal cursor.
• Press the CURSOR button to enter the cursor measurement menu. Then press the
F1 key to select the type to voltage.
• Press F2 to select the source of the voltage measurement channel and set the
pattern to independent.
• The multi-purpose control can be used to adjust the horizontal cursor AY on the
screen, press the multi-purpose control to switch to cursor BY. The value of BY-AY
is the voltage measurement (V).
